MECHANISM FOR SETTING TYPE IN MAKING STEREOTYPE-PLATES.

. l Specification forming part of Letters Patent N0. 52.073, dated January 16, 1866.

To all whom it may concern: 7

' Be it known that I, JOHN PAULDING, ofthe city, county, and State of New York, have invented certain new and useful Improvements inMechanismifor Settinglype' foirTMaking Stereotype-Plates and forotherPurposesj and Ido hereby declare that the followiiigis. a full description of the same.

The object of my invention is toprepare the use of a perpetual font of type, so arranged in a typeholder that a line of matter may be set up and impressed upon the clay or other plastic com- ,pound, and the type again restored to their original position without removal from the type-holder, and thus not only quicken, but also chea pen, the process of making stereotypeplates; and consists, rst, in theuse of a revolving typeholdef, second, in the combination, with the revolvingtype-holder, of a series of rows of type, attached to the end'sjof thin strips or rods of steel wire working or sliding in grooves or channels cut in the type-holder so as -to allow of their extension belowthe'holder to take the impression in the clay or other plastic compound used; third, in the use of the strip of steel or wire, in combination with the type having notches cut in their edges for adjusting and holding them in place-in the stock,

" and also gaging the depth ofi their fall when setting up the type; fourth, in the use of a type-setter, in combination with the typeholder for the purpose of setting the type,

to the next series, that the entire line of matter may be setup without change of the typeand as each type is set automatically moving setter; fifth, in the use of the gage-notch in the sideor edge of the type, in combination with a. straight-edge slide for formingthe type-letters into a line and holding them in that position till an impression in the clay or other plastic compound has been taken;

To describe my invention more particularly, I will refer to the accompanying drawings,

forming a part of the specification, the same letters of\' references, wherever they occur, referring to like parts. Figure 1 is a side elevation of the mechanism. Fig. 2 is anend View of the same. Rig:

Fig.4 is a One of the rows o WW the nature of my improvements 'longitmlinalcut section 'of the machinethrough theline' w w,Fig.2, showing the position of and held inplace by the sliding straight-edge. Fig. is a plan view at the machine. Fig. 6 is' a detached plan view of the t 'ie-setter taehed view ot'one of the type as secured to the end of the adjusting rod orwire. Fig. 8 is an end view of the machine, showing a row of letters set up and .coin1.)res se(l by means ofpins or set-screws passing transversely through the machine on aline-with the sliding straightedges. I

Letter ,A is the name of the machine,which uiay be made of wood or any other suitable material. In this frame is adjusted on center plus, B, a type-holder. 0, of-such form and size as deemed requisite. This type-holder is intended to be divnled into as many rows of difierent type aswill conveniently fall into the line by gravitation, each row posed of the same letter of type, and having a number of such similar type as will be equivalent {loathe number of type of all sorts used in' a e 'tobe printed, the said rows of similar type running parallel to the line to be set, and will contain the. alphabet, spaces, and punctuations most commonly used and required to make up a line of matter. In the drawings thisis represented by four rows, having a series of 'five type of the'same sort, as as inone row, es in the second row, is in the third row, and os-in the fourth row. These type are combined withan adjusting-rod composed of a thin piece of spring-steel. The object of this is to admit of the ready adjustment of the type in a line by means of the sliding straight-edges F, as shown in Fig. 4, and their lateral adjustment or compression, when inn-line, by the coin pressorpins orscrews G, as shown-in Fig. 8. In this .figure will alsobe illustrated the operation of setting the ,line of type-matter up where the series of letters are the vowel letters and the vowels a, i, o, are to be stereotyped.

As shown in Fig. 4, the type-setter H, moving on slides I, secured to tlze'top of the typeholder, is adjusted over the first line of .the seriesof difl'erent sorts of'type, and the key untouched, when the letter it drops andis held by a gage notch, K, in the adjustment-rod from dropping out of the type-holder. The setter is then moved over, either automatically Fig. 7 is a de-- being comor b hand, to the nextline of the series ofdifiercnt etters,when.the letter i is dropped by the hey i, and thence to the next line of the series to drop the letter 0 in the like manner by the key 0. Wh'en.the type-matter is thus set. up, as it may be said, it is locked or,compressed together by the screws G, while they are held in line by the sliding straightedges engaging in the notch "J, cut in the side of the-type.

While in this position. the impression istaken by means of a matrix of clay or other suitable jplastic'componnd. This is done by-forminga proper box or bed, with the lines partitioned elf to prevent compression, and sliding it nn-' derneath the type, and, by means of any c0inmen and well-known 'devlce, raising it up against the faceof 'the' type, which, immedi,

ately the impression has been taken, is lowered and moved forward for the next line of written When this is done the type are unlocked and the type-holder reversed, as shown in Fig. 3, by taking hold of the handle L and carrying it around till it rests inthe notch M, formed by cutting awaya portion of the frame of the machine. By this means the type readjust themselves, in consequence of the notch mat the upper end of the adjusting-rod,.latching on a detent-plate, P, forming the edge of the-crows of type. The type-h0lder is then readjusted, and by means of the type-setter the newline of type-matter is set up, as before described, and thus progressivelytillthewholc page of matter is'tinished.

lt-will be obvious that for special and varied characters of typedll-t'erent fontsof type can be used; also, that capital letters and otherpecnliar script canbe inserted as separate type in place of the type ordinarily used. These modifications, of course, can be readily understood, as also that of making the font large enough to hold a suflicient number of type to make a line for the largest sized page of matter.

In moving the type-setter t 1s contemplated 'in the manner thatan automatic attachment will be used, so that as each key drops a type as the key rights itself again it will carry the setter forward over the next line of type, and thus leave the operator only the task of indicating the letter to be dropped, as hereinbetore described.

Having nowdescribed my'iuvent'ion, I will proceed to set forth what I claim and desire to secure .by Letters Patent of the United S ates:

1. A revolving type-holder, as hereinbefore described, for the purpose of rea'djusting the type, as set forth.

2. In combination with the typeholder, a series of rows of adjustable type having a guidespring rod attached thereto, and arranged with respect to each other substandaily as described 3. The method of adjusting the type in the type-holder'by means of ene or more stops or catches, n and K, on the edge of the guide-- spring rod attached thereto, substantially as described.

4. The sliding type-setter H, in combination with the type-holder 0, when operating in the manner and for the purposes hereinbefore set forth.

5. A gage-notch, J, formed in the body of in combination with a straight-edge slide, F, when operating for the purpose and substantially as hereinbefore described.

6. The general combination of all the said several parts of the said machine, as enumerated in the five preceding claims, as a means of impressing the forms of type in a plastic mold for making stereotypeplates, by the single line or part of a line, froma perpetual font of type, snbstantiallyas hereinbefore set forth.
